Parker Lucifer 341N01 NAMUR Solenoid Valve

Overview

The Parker Lucifer 341N01 solenoid valve is a heavy duty NAMUR spool valve from the Parker N-Series, designed for the pilot control of pneumatic actuators in process control applications. The valve is a NAMUR indirect operated (pilot operated) spool valve, solenoid or air operated, delivering a range of functions including 3/2, 5/2 and 5/3, and this example is identified in the original listing as a 5/2-way valve with 24 V dc coil, IP65 protection and 2-10 bar working pressure.

The N-Series valves are built for the demanding environment of process plants, where they control the air to quarter-turn actuators and other pneumatic devices on valves, dampers and similar equipment, with the NAMUR interface allowing direct mounting on the actuator without additional piping.

Engineering & Design

The 341N01 solenoid valve is a pilot operated spool valve with an anodised aluminium body and NBR seals, and the official Lucifer datasheet identifies the housing reference 8993 with coil reference 488980 for this configuration, assembled as 341N01-8993-488980. The valve has G1/4 connections on the NAMUR interface, a nominal orifice of 4.0 mm and a flow factor Qn of 400 L/min at 6 bar inlet with 1 bar differential pressure, with an operating pressure range of 2 to 10 bar.

The integrated pilot allows direct solenoid operation, and the valve body can be configured across the 3/2, 5/2 and 5/3 function range of the N-Series family. The working temperature range is -25 °C to +80 °C for the standard coil configuration, and the protection class is IP65 with a connector coil.

Key Features

• Heavy duty 341N01 solenoid valve, NAMUR pilot operated, for process control
• Full N-Series function range: 3/2, 5/2 and 5/3
• G1/4 NAMUR interface, 4.0 mm nominal orifice, Qn 400 L/min
• Working pressure 2-10 bar, NBR seals, anodised aluminium body
• 24 V dc coil, IP65 protection class (per original listing)
• Assembly reference 341N01-8993-488980 (housing 8993, coil 488980)

Applications

• The 341N01 solenoid valve provides pilot control of pneumatic actuators on process valves
• Control of quarter-turn and linear actuators via NAMUR interface
• Fail-safe and on/off control in process plants
• Replacement duty for existing N-Series NAMUR valves

Specifications

Compatibility & Integration

The 341N01 solenoid valve mounts directly on pneumatic actuators with a NAMUR interface, and the solenoid coil connects to the plant control circuit. The 24 V dc coil version integrates directly with PLC and relay outputs, and the valve can be specified with different coil voltages and protections, including Ex versions available in the N-Series family.

Before installation, confirm the required function (3/2 or 5/2), the actuator air consumption and the plant air supply pressure against the valve rating. Our team can confirm the configuration and function details against your application before dispatch.

FAQ

Confirming the Exact Configuration

The N-Series covers several functions and coil options under closely related references, so a replacement for this valve should be checked against the full assembly reference rather than the base number alone. The markings to look for are:

• The base reference 341N01 on the valve body.
• The housing reference 8993 and the coil reference 488980, together forming the assembly reference quoted above.
• The coil voltage and connector type, and any hazardous-area marking.
• The function in use on the actuator (3/2, 5/2 or 5/3), which affects what can be fitted as a direct replacement.

Installation on the Actuator

Before fitting, confirm that the actuator uses the standard NAMUR pattern and that the mounting screws and O-rings are in good condition. Supply the valve with clean, dry instrument air, as heavy-duty spool valves are robust but still sensitive to water and particles in the air. After mounting, cycle the actuator several times and confirm stroke times against the process requirements. Where faster or slower stroking is needed, speed control is normally added in the exhaust ports rather than by restricting the supply.

Maintenance and Troubleshooting

Include the 341N01 solenoid valve in periodic valve function tests. Signs of trouble include audible exhaust leakage at rest, delayed switching after the coil is energised, or a coil that runs hotter than usual. Replacing the coil or the complete valve is usually quicker than in-situ repair on a running plant, which is why many sites keep a spare on the shelf.

Process Plant Use in Oman and the GCC

Heavy-duty NAMUR valves are common on shutdown valves, tank outlets and utility valves across the region, where they must operate reliably after long periods without movement in hot, dusty conditions. Seven Star LLC supplies this Parker Lucifer valve for replacement and project needs, and confirms the housing and coil references before dispatch.
